>Description</H2
><P
>   <TT
CLASS="COMMAND"
>CLOSE</TT
> frees the resources associated with an open cursor.
   After the cursor is closed, no subsequent operations
   are allowed on it. A cursor should be closed when it is
   no longer needed.
  </P
><P
>   Every non-holdable open cursor is implicitly closed when a
   transaction is terminated by <TT
CLASS="COMMAND"
>COMMIT</TT
> or
   <TT
CLASS="COMMAND"
>ROLLBACK</TT
>.  A holdable cursor is implicitly
   closed if the transaction that created it aborts via
   <TT
CLASS="COMMAND"
>ROLLBACK</TT
>.  If the creating transaction
   successfully commits, the holdable cursor remains open until an
   explicit <TT
CLASS="COMMAND"
>CLOSE</TT
> is executed, or the client
   disconnects.
